God of War: Ascension - Empusa

The Empusa is a smaller and very agile enemy that Kratos encounters a few times throughout the game. The Empusa has blades for arms and legs, which it uses to do melee attacks, including a three-hit combo. It can also latch onto your back, which you can shake free by bouncing your left analog stick left and right. One last attack it can do is hitting the ground with both "hands," creating a circle of acid on the ground, which you'll take continual damage if you stay within it.

Keep attacking it and eventually a red halo will appear over the Empusa. Grappling it will have Kratos automatically kill it, yielding blue and red orbs.
